Sweetheart Trailer (2011)

The 1950s, and the height of Cold War tension: When her husband and stepsons don’t return from a routine trip, a young housewife finds herself alone in their remote farmhouse. As it becomes clear that they are not coming back, she must force herself out of an aimless cycle, setting off to find them.

What she finds instead is a seemingly derelict world, empty of all but a few dazed 'survivors'. Unsure who, if anyone, to trust, she must navigate a series of strange encounters to find answers in a world that, with a undercurrent of future science beneath its surface, will reveal itself to be a marked alternative to the world we remember.
